4. Specic Areas of Danger, Cauon or Warning
Electrical Shock
WARNING! Electric arc welders can produce a shock that can cause injury or death.
Touching electrically live parts can cause fatal shocks and severe burns. While welding, all
metal components connected to the wire are electrically hot. Poor ground connecons
are a hazard, so secure the ground lead before welding.
• Wear dry protecve apparel: coat, shirt, gloves and insulated footwear
• Insulate yourself from the work piece. Avoid contacng the work piece or ground
• Do not aempt to repair or maintain the welder while the power is on

as possible
• Do not touch the welding wire and the ground or grounded work piece at the same
me
• Do not use a welder to thaw frozen pipes
Fumes and Gases - WARNING!
• Fumes emied from the welding process displace clean air and can result in injury or
death
• Do not breathe in fumes emied by the welding process. Make sure your breathing air
is clean and safe

Operators Manual

• Work only in a well-venlated area or use a venlaon device to remove welding
fumes from the environment where you will be working
• Do not weld on coated materials (galvanized, cadmium plated or containing zinc,
mercury or barium). They will emit harmful fumes that are dangerous to breathe. If
necessary use a venlator, respirator with air supply or remove the coang from the
material in the weld area
• The fumes emied from some metals when heated are extremely toxic. Refer to the
material safety data sheet for the manufacturer’s instrucons
• Do not weld near materials that will emit toxic fumes when heated. Vapors from
cleaners, sprays and degreasers can be highly toxic when heated
UV and IR Arc Rays
DANGER! The welding arc produces ultraviolet (UV) and infrared (IR) rays that can cause
injury to your eyes and skin. Do not look at the welding arc without proper eye protecon.
• Always use a helmet that covers your full face from the neck to top of head and to the
back of each ear
• Use a lens that meets ANSI standards and safety glasses. For welders under 160 Amps
output, use a shade 10 lens; for above 160 Amps, use a shade 12. Refer to the ANSI
standard Z87.1 for more informaon
• Cover all bare skin areas exposed to the arc with protecve clothing and shoes. Flame-
retardant cloth or leather shirts, coats, pants or coveralls are available for protecon
• Use screens or other barriers to protect other people from the arc rays emied from
your welding
• Warn people in your welding area when you are going to strike an arc so they can
protect themselves
Fire Hazards
WARNING! Do not weld on containers or pipes that contain or have had ammable,
gaseous or liquid combusbles in them. Welding creates sparks and heat that can ignite
ammable and explosive materials.
• Do not operate any electric arc welder in areas where ammable or explosive
materials are present
• Remove all ammable materials within 35 feet of the welding arc. If removal is not
possible, ghtly cover them with reproof covers
• Take precauons to ensure that ying sparks do not cause res or explosions in hidden
areas, cracks or areas you cannot see
• Keep a re exnguisher close in the case of re
